Abstract

Method and apparatus for facilitating detection of a presence or an absence of at least one underground facility within a dig area. At least one marked-up digital image of a geographic area including the dig area, the image including at least one indicator to delimit the dig area, is electronically processed by converting the at least one indicator to a plurality of geographic coordinates representing the delimited dig area. Information relating to a locate request ticket identifying the dig area to be excavated is electronically transmitted and/or electronically stored, wherein the locate request ticket includes image data and non-image data associated with the dig area. The image data includes the at least one marked-up digital image of the geographic area surrounding the dig area, and the non-image data includes the plurality of geographic coordinates representing the delimited dig area.
